Ishibashi Haruko, aka the cyborg superheroine Masked Saver Flash, was once modified by the evil secret organization Zemmasaka. Now she teams up with Tachikawa Heihachi, aka "Old Man Tachikawa," to continue fighting against Zemmasaka. One day, Zemmasaka devises a plan to kidnap Tachikawa Heihachi in order to uncover Flash's weakness. However, the villain Assaultgorn, assigned to carry out the kidnapping, is defeated by Flash, causing Zemmasaka to lose yet another villain. As punishment for this failure, the foot soldiers are disciplined by the female executive, Jigoku Kaijo. But due to the soldiers' masochistic nature, the punishment is actually welcomed with pleasure. Meanwhile, Flash realizes the kidnapping was merely a diversion, and the true objective was a bombing terrorist attack. Flash opposes interrogation through torture, instead attempting to undermine the soldiers' pride through sexual humiliation. However, for the soldiers, this only amounts to delightful treatment. As a result, Flash's plan fails, leading to a BAD END.
